DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, in order to achieve the above functions, the technical solutions adopted by the present invention are as follows: A portable leveling staff, including a storage box 1, transparent display boards are provided on both side walls of the storage box 1, and a box cover 2 hinged to the storage box 1. It also includes an adjustable leveling staff assembly 3 disposed in the storage box 1, and a portable moving assembly 4 disposed on the storage box 1. A vertical plate 5 is fixedly provided on the inner bottom wall of the storage box 1.

[0022] As Figures 3-4 shown, the adjustable leveling staff assembly 3 includes a rotary motor 6 fixedly provided on the side wall of the vertical plate 5. The output end of the rotary motor 6 is connected to a transmission rotating plate 7. The other end of the transmission rotating plate 7 is fixedly provided with a transmission gear 8. A connecting seat 9 is rotatably connected to the transmission gear 8. The connecting seat 9 is arranged in a cross shape. A driven gear 10 is meshed with the transmission gear 8. A lighting strip is fixedly provided on the driven gear 10. Scale rulers 11 are fixedly connected to the side walls of the transmission gear 8 and the driven gear 10. Scale bars are evenly arranged on the scale rulers 11. The scale rulers 11 are symmetrically arranged at both ends of the connecting seat 9. A rotating rod 12 is rotatably provided at the other end of the side wall of the vertical plate 5. A driven rotating plate 13 rotatably connected to the connecting seat 9 is fixedly provided on the rotating rod 12.

[0023] As Figure 2 shown, the portable moving assembly 4 includes a base 14 fixedly provided on the bottom wall of the storage box 1. The base 14 is symmetrically arranged at both ends of the bottom wall of the storage box 1. The base 14 is arranged in an inverted U shape.
